Y This invention relates to'improvements in car'construction. Y, .g

Oneobject of theL invention isV to'provid'e a combined `lockingand center` pin arrangef ment'for railway car bolsters, which is of exceptional strength andpresents eXceptionally great cross sectional area to yresist shearing, whereby the v carftruclr and body are .maintained in substantial connection',espe

cially in the event of collision,to avoid telescoping of the cars of trains.

A more specificobjectjof the invention is' to provide aV combined center and locking pin arrangement `for connecting ythe bodyk and truck bolsters of a car; having alined center pin receiving openings, includingv a solid pin headed at oppositeends andlhaving shouldered engagement kwithv the body and' truck bolsters, respectively, to prevent sep-v` aration thereof, the head at oneend of the pin or the heads `atboth eindsbveingv cutaway' at opposite sides and' the opposite wall por-a tions/of each pin'receiving'opening of`y the bolstersbeing slotted to permit insertion ofi the' pin when 1n one position,th'efpin'belngjv rotatable to Yanother position to engage the solid portions of the cut-away heads'withY the shouldered portions of thecorresponding bolsters,fthe pin being locked; against'prota-v tion with respect to said bolsters by .an ele' ment havingleg portions disposed withinl the/slots of the bolster pin receiving open-r ings and occupying the space between the; sides of the pin and the opposed walls of the slots to brace the pin and increase the eifective cross sectional area thereof.

In said drawings, the body bolster *of the railway car is indicated bythe characterl y10 and cooperates with a truck bolster ""11. The bolsters are provided with alined centen pin receiving openings and the truck bolster is provided `with a pocket 12 at 'the 'upperv side thereof, in which bearingjblo'ck 13` n of well known design is seated. Therbeal-,

ing, block 18 is provided with aspheri'cal bearing surface 14 atjtheupper sidethereof` which cooperateswith a'sphe'rical bearing' surface 15 formed at the bottom side of the, body bolster. The bearing block 13 is also providedV Vwithl an 'upstanding central yportion 16 which engages within `f an opening 17 formed in the bottom of the body bolster.

In carrying vout our invention, we provide lthe truck bolster with al pin receivingopeningj18 and an adjacentpocket 19 ,whichfam cominodates the head of the combined 'lock-V ing and center pin. The opening 18 is laterj ally enlarged at diametrically opposite sides,

as indicated at 20-20, therebyl leaving shoulders 21-21 which form abutment means for' the head of the lockingV pin. The opening in, the.. bearing block 13 is of the same conf-g `tour as the opening in the;r bolster 11y 'and' registerslthere'with. A y

rThe body bolster Y, 10 is yprovided with van Vopening 22 which is of enlarged cross sectionalfarea adjacent the'bottom portion of lan'ges or ribs 24and l25 are provided. rljhe lang'es 24land 25 are cut away atoppositeA sides,.thereby providing openings 45-45, the

outer walls 'of which/coincide with opposed wall portions of the enlarged section of the opening 23. Above the tlange'24, the openfing ofY the bolster 10. providesl a pocket 26 which accommodatesthehead at the upper 'the`bolster5 yas indicatedat23.

. The Venlargements v28-7-28 *and 29-29 are lV 'l l 1d of suchasizeas to pass freely; through the i enlargedportion'of the opening '18 of the bolster 11' Vand also the cut-away-portions of the 'flanges 24 and25. As will be evidentythe locling pin .may ythus be freely `inserted through either 4the truck or body bolster when the-*enlargements'28-28 and 2'9.-29 at the opposite endsofthe pin are in alinement with.v the laterally enlarged sections Vof the opening 18v and they cutaway portions of the flanges 245 and of the bolster 10, and when-the pin is rotated, after having been assembled with the bolsters, the enlargements 28-28 andA 29-,29 are brought'into overlapping relation with the shoulders 21-21 and-theflange 24, thus f Toprevent accidental dis lacement ot the `locking pinywe rprovide'a U-shaped locking membe'r 30 having depending leg portions SlT-#31 which.` straddlejthe shank of the pin and have flat inner ffac'es 32`32which embrace the opposite sides of the pin, the pin' having the 4cooperatingsides thereotattened, as indicated Vatyto lit thefaces of theleg portions. YThe connecting top portion of the U-shaped locking member lits over the upper end ofthe, pin and the upper pcrtions of the legs 31-31`are disposed .be-

Y. Vtweenthe enlargements 29-29 oi the' pin.

As most clearly shownl inrlligure's 2, and 3,'

the leg portions 31-31 extend "entirely i* through the bolsterlO-Vand into the laterV- ally enlarged portionsof the opening 18 ofl the bolster 11, with the lower extremities Vthereof between the enlargements 28e-28 at the lower end of theypin.` The upper secrelative angular rotation' of the pin' and the bolster11 is thus permitted. lheparts tions of the leg portions 31 are'of such a width and Ythickness as to `fully occupy the cut-away portions of theflanges 2stv and 25 `and fill ythe spaceY betweenthe faces/SB-vjot the Ypin andv side wall portions of the opening in the bolster 10. Y A Y The. .bottom end portions. of, the legs 31 which extend into the lpin receiving opening of the bolster '11 are reduced in'width,` as indicatedfat 374i, thereby leaving a certain amount'of clearance between the side edges of the-,same and the transverse wall sections of the enlarged portions of Athe opening'18. As will; be evident,l a. certain amount of are so proportionedthat the amount of rotationV permitted issu'hcient to permit the proper angularturning of the1bolsters with respect to each other when cars are operated on track of maximum curvature encountered in .standard railway practice.Y

In connecting the body and truck bolsters of a car, the pin mayv be inserted either- `through the truck orbody bolster. Whenthe same is'inserted through the truck bolster, thesame-is passed upwardly through i are disposed above the V*flange 2%,"theV pin is given a partial rotation tobring kthe enfully' inserted sothatthe enlargements 29, Y Y

largements intobverlapping relation with Y thefull sections of the liange 2e. l This position of the pin is shown in Figuresjl andv 2l of the drawing. The locking element 30" is then applied by placing the same over the'upper end of' Vthe pin Awith the legs thereofv 1n registration withl the cut-away Yportions of the flanges 24 and 25. Y

The locking element is thenforced down.- wardly until the section connecting Ythe up-` per'ends" of the legs rests on topV of the pin` and the leg members are'engage'd within Athe cut-away portions of the ianges 24C and 2 5 and the enlarged sections of Vthe open--Y ing 18 of the bolster 11'.Y lt will be evident thatthe locking element will thus positively prevent Vrelative'rotation between the pin and the bolsterlO, and,` due to thereduced width of' the lowerend-portions of` the legs, will\ permitthe'necessary amount Inasmuch as the member occupy the space between the pin and the opposed wallsy of the openings in the holsters, the legs'serve to increasethe effective cross sectionalfarea of the pin,v

thereby increasing considerably its capacity to resist shear-whlch is very important 1n railway car construction.r

Vhen it is desired to insert the retaining f pin through the body bolster, the assembling op'eration is performed in a similarV manner'to that hereinbefore describechthe enlargements 28--28 at the bottom end of the pin kbeing brought into registration with.

the cut-away'por'tions of theanges 2-1 and 25 and the enlarged` sections of the opening 18 of the bolsterill. After vthe pin has l beenrotated, we bring the enlargements 29jofirelative rotation `between `'the pin and ""j. the'bolster 11. Y Y

legs Vof the U-shapedn' 29 in overlapping relation-to tliefiange 24(Vv i and the enlargements 28 in overlappingrelation with the shoulders 21.; the Y pin is locked bythe member 30, bygpassing the same'y overI the top of lthe pin` in v the: manner hereinbeiiore pointed out. s v A,

rWhen it ,is desired to separate .the body and truck, bolsters-of the car, it is merely necessary to withdraw the locking elementr 30 and vrotate the pin until the enlargements 29 register withthe cut-away portions of the iianges 24 and 25, and the enlarged sections of the opening 18 and withdraw the pin from either the truck or bodybolsten While we have herein shown and described what we consider the preferred manner of carryinfr out our invention, the sameis merely illustrative and we contemplate all changesy and modications which" come within the scope oi' theclaim appended hereto.
